Thick Film Hybrid IC
STK795
Chopper Type Voltage Regulator
Features
• Self-oscillation type chopper regulator power IC using
Sanyo’s original IMST (Insulated Metal Substrate Tech-
nology) substrate.
www.DataSheet•4UT.hceomSTK795, being a 5V chopper IC, is more advanta-
geous in the following points as compared with series
regulator (dropper type) ICs.
1. Possible to provide a 5V output power supply circuit
with high efficiency.
2. Since the input voltage range is wide, no more than
one rectifying/smoothing circuit is required to pro-
vide a multi-output power supply circuit which also
delivers 12V or 24V output.
• Functional trimming is used to set 5V output with high
accuracy.
• Cutoff function to cut off output voltage by external sig-
nal.
• Contains a transistor for overcurrent protector (foldback
characteristic) and possibel to set the protection level ex-
ternally.
